The TOP CROLL L integrates a CROLL L ventral rope clamp to transform the ASTRO SIT FAST, AVAO SIT, AVAO SIT FAST, FALCON, FALCON ASCENT and SEQUOIA SRT seat harnesses into rope access harnesses. The foam shoulder straps are widely spaced to reduce neck chafing. When the waistbelt is loaded, they help distribute the load over the shoulders.
